What is a Bitumen Bag Decanter ?
A Bitumen Bag Decanter, also referred to as a Big Bag Bitumen Melter or Bitumen Decanter, is an industrial system developed to melt bagged, block or solid bitumen before it is transferred to production or storage.
The bitumen is heated indirectly by circulating thermal oil through specially designed heating surfaces. This method prevents overheating while maintaining the original physical properties of the bitumen and ensuring a safe, energy-efficient melting process.
Technical Specifications of the Bitumen Bag Decanter
High Performance and Continuous Bitumen Melting
5–10 TPH Melting Capacity: Designed to meet the high bitumen demand of asphalt production, the Bitumen Bag Decanter provides a melting capacity of 5 to 10 tons per hour, ensuring continuous and efficient operation.
Easy Big Bag Loading System: Equipped with an integrated electric hoist, the Big Bag Bitumen Melter allows heavy bagged bitumen packages to be safely lifted and loaded into the melting chamber with minimal operator effort.
Thermal Oil Heated Melting System: Specially designed thermal oil heating coils rapidly melt bagged and solid bitumen while preserving its original properties. This indirect heating system ensures fast, uniform and energy-efficient bitumen melting.
Continuous Operating Cycle: The integrated bitumen collection chamber enables uninterrupted melting and transfer, allowing the Bitumen Decanter to operate continuously for maximum production efficiency.
Smart Safety and Control Systems
Temperature-Controlled Bitumen Transfer: Once the bitumen reaches its liquid state in the collection chamber, it is transferred safely through the Bitumen Bag Decanter using intelligent temperature monitoring. The transfer process can be operated automatically or manually for maximum operational safety.
Integrated Bitumen Pumping Station: The melted bitumen is transferred quickly and efficiently to storage tanks through the heavy-duty bitumen pumping station integrated into the Big Bag Bitumen Melter, ensuring continuous production with minimal heat loss.
Overflow Protection System: To prevent overflow and ensure safe operation, the integrated bitumen collection chamber is equipped with a high-sensitivity float level control system as a standard feature.
Energy-Efficient Thermal Insulation: High-density thermal insulation minimizes heat loss, maintains the required bitumen temperature and reduces fuel consumption and overall operating costs.
Operator-Friendly Design: The Bitumen Decanter features an ergonomic design that allows operators to control the entire melting process easily, safely and efficiently without complex operating procedures.

How Does a Bitumen Bag Decanter Work ?
Our Bitumen Bag Decanter operates through an intelligent 4-step melting process, converting bagged bitumen into liquid bitumen quickly, safely and with minimum energy consumption. Designed for continuous industrial operation, the system ensures high productivity while preserving the quality of the bitumen.
Step 1: Safe Loading (Electric Hoist System)
Heavy Big Bag bitumen packages are transported from the storage area and safely lifted using the integrated heavy-duty electric hoist system. Without the need for additional lifting equipment, the bags are positioned directly into the loading chamber of the Big Bag Bitumen Machine, ensuring fast, safe and efficient loading under operator control.
Step 2: Thermal Breakdown and Rapid Melting
The bagged solid bitumen placed in the loading chamber comes into direct contact with the specially designed thermal oil heated coils (high-temperature heating tubes). Thanks to the high-density thermal insulation, heat loss is minimized, allowing the thermal energy to be transferred directly to the bitumen for fast, uniform and energy-efficient melting.
Step 3: Continuous Filtration and Intelligent Level Control
As the bitumen melts, it flows into the integrated bitumen collection chamber located beneath the melting section. This chamber ensures a continuous melting cycle, allowing uninterrupted operation of the Bitumen Bag Decanter. The liquid bitumen level is continuously monitored by a high-precision float level control system, providing reliable overflow protection and safe operation.
Step 4: Temperature-Controlled Automatic Bitumen Transfer
The temperature of the melted bitumen stored in the bitumen collection chamber is continuously monitored by intelligent sensors. Once the bitumen reaches the optimum pumping temperature, the transfer process can be operated automatically or manually through the PLC control panel.
The integrated high-performance bitumen pumping station transfers the liquid bitumen quickly and safely to bitumen storage tanks, asphalt mixing plants, PMB plants or bitumen emulsion plants with minimal heat loss, ensuring a continuous and efficient production process.

Frequently Asked Questions About Bitumen Bag Decanters
Find answers to the most common questions about selecting the right Bitumen Bag Decanter, melting capacity, thermal oil heater integration and safe operation for asphalt production projects.
Is an external thermal oil heater required to operate the Bitumen Bag Decanter ?
Yes. A thermal oil heater is required to generate the heat energy needed to melt bagged and solid bitumen efficiently. If you already have an existing thermal oil heating system at your plant, our Bitumen Bag Decanter can be integrated into it. If not, MBA Plant supplies a complete turnkey solution, including the thermal oil heater, bitumen storage tanks, piping system and all auxiliary equipment.
Is Additional Lifting Equipment Required to Load Big Bag Bitumen into the Bitumen Bag Decanter ?
No. Our Bitumen Bag Decanter is equipped with a heavy-duty integrated electric hoist system as standard. Operators can safely lift and load Big Bag bitumen packages directly from ground level into the melting chamber without requiring additional lifting equipment. This design improves workplace safety while eliminating the need for cranes or forklifts during the loading process.
Is the Bitumen Bag Decanter Suitable Only for Standard Bitumen, or Can It Also Melt Polymer Modified Bitumen (PMB) ?
Yes. Our Bitumen Bag Decanter is designed to process both standard penetration grade bitumen (such as 50/70 and 70/100) and Polymer Modified Bitumen (PMB). The system is equipped with high-efficiency thermal oil heated coils capable of reaching and maintaining the higher temperatures required for PMB. Combined with high-density thermal insulation, the unit ensures stable operating temperatures, uniform melting and consistent bitumen quality throughout the process.
Can the Big Bag Fabric (Polypropylene Bag) Damage the Bitumen Bag Decanter if It Falls into the Melting Chamber ?
No. The Bitumen Bag Melting Machine is designed with a specially engineered thermal oil heated grate system that allows only the melted bitumen to flow into the bitumen collection chamber. The outer polypropylene bag remains on top of the grate and is prevented from entering the bitumen transfer pump or connected piping system. Once the melting process is complete, the remaining bag material can be easily removed by the operator, ensuring safe, clean and uninterrupted operation.
